What makes it different
  • Human-approved mandates enforce intent, not just static limits or merchant category blocks
  • Operates outside the agent in the issuer's authorization path, preventing agent bypass or override
  • Creates tamper-evident audit trail linked to agent identity, run, and policy version
  • Never holds funds or issues cards; integrates with existing issuer infrastructure
  • Single mandate and policy core across multiple payment rails and issuers
  • Turns failures into replayable learning environments
  • Prevents regressions by keeping previous evals in the loop
  • Integrates with existing observability stacks and traces
  • Preserves business intelligence versioned in repository
  • Adapts harness to model changes without redefining use cases
